Scope
JB/T 12562-2015 is the English-translated version of 低压铸造机 性能检测方法.
JB/T 12562-2015 is the recommended Chinese machinery industry standard that sets out how the performance of low pressure die-casting machines is to be tested. It gives the terms and definitions, the test items, the test conditions, the instruments used for the measurements, and the testing methods themselves.
It applies to the low-pressure casting machine used to produce aluminium castings by the low-pressure casting method, called the casting machine in the text. One document is applied with it, GB/T 28688.
